Update: I haven't deciphered anything more, but as I write up my findings in the Peter Keith bio, I've convinced myself that this is not a bequest to Oriane and almost certainly a repayment of a loan. 1) The testament Eva produced doesn't mention anything about additional beneficiaries. 2) I've seen other cases where the creditors get paid before anyone can inherit, which is still a thing today in the US, afaik. So that would explain why Oriane gets her money before anyone else, and she gets a say in whether the seal is lifted without inventory.

I think Peter and Oriane lent money to James Keith!
